See your data. Know your data

We’re getting a lot of users that want to customise the way Iolite processes their data, which is really exciting as it’s exactly why we built Iolite in the way that we did. But we realise that there may be many more that just find getting into the programming code a little too intimidating, or…

This is just a quick tutorial to show you how to add more global variables or global strings to a DRS. These globals are useful because they’re acessible via the Edit Settings window, which means that people not comfortable with the code can quickly and easily view and modify them (e.g., the “ReferenceStandard” global string).…

We’ve had a bit of interest in propagation of uncertainties in Iolite, so I thought I’d try to do two things in this post and the next. In this post, I’ll have a go at describing our protocol for propagating uncertainties. There is a description of the method in Paton et al. (2010), but I’ll…

In this post I’m going to give a description of how someone making or modifying a DRS can take advantage of the DRS support functions included in Iolite for working with splines. I’ll use the existing “Sr_isotopes_REE” DRS as an example – it’s distributed with Iolite, which should make life easy for anyone that wants…

The ease with which you can rapidly switch between different elements for internal standardisation and different reference materials for external calibration (see last post) is one of the great strengths of Iolite. This can be extended to the DRS level too. If, for example, in addition to standard U-Pb geochronology, you wish to do some…

Those new to Iolite will notice that there are two version of the Trace elements DRS, called simply Trace_Elements and Trace_Elements_IS. Which one do I use? Well, if you are analysing a whole bunch of samples with similar major element composition (e.g. speleothems or corals where you can reasonably expect stoichiometric behaviour), or you are…

As Jon mentioned recently on the forum, a paper detailing much of Iolite’s functions and features is now available as an Advance Article at JAAS.The article describes the main features of Iolite, and provides details of the main processes of data reduction (including how statistics are calculated).There is also an online supplementary info file that…

We’ve had a few questions regarding how Iolite estimates down-hole fractionation (in the U-Pb DRS), and several people have also had problems reducing their data because the algorithms didn’t work as they should.So, I figured it might be useful to describe a bit about how the depth is estimated, and more practically to explain how…

Version 2.14 is now available for download from the Iolite website at www.iolite.org.au New features in the latest release include: -All statistical code is now unencrypted and collected in the file “Statistical functions.ipf” -Fixed a bug that affected the rounding of certain numbers in the Report Window and exported files -You can now export your…

Hi all, As you may be aware, the Iolite team have been busy working on a new release and the Iolite workshop (August 14th) as part of the Goldschmidt conference. But the forum has been busy with interesting and important questions asked by users. I recommend having a quick look at these topics: There’s a…
